  • making external drive USB powered

    Hey just a quick question.

    I bought a Sony DRXS70U EXTERNAL SLIM DVD BURNER USB but its powered by a AC adaptor. The AC adaptor pumps out 5.2Volts and 2 Amps. If I where to cut a USB cable and use the power cables from it and attach them on a power plug for the drive would this work.

    Drive 5.2V - 2A
    USB Power 5V - .2A

    I think the Volts should be ok but will it still be able to work even with the amps a lot less then needed??


    Thanks, Dave.

    at the risk of embarrassing my physics teacher many years ago.. Power is the Voltage (V) multiplied by the Current (I) plus

    V
    I R

    so you would have too much resistance to get this working.

    Power would be 10.4 or 1 which is a big difference.

    It was many years ago though...
    cheers

      Hi,

      Saving you the hassle on cutting through the wires and patching (unless you enjoy doing it ) have a read on:

      Sony states that it can't be powered from a USB port, and includes a mains power adaptor, which limits its usefulness as a laptop accessory. However, we found that it worked fine when powered using a 5V-to-USB adaptor cable from www.solentcables.co.uk for 2. It's puzzling why one wasn't included in the first place.

        If I'm not mistaken the USB spec provides for only 450mA from a USB port. You're drive requires 4 times that amount so it would not work. also, it would not be adviseable from a safety perspective.
